WebSep 25, 2024 · How many triangles can you draw? You can only draw one triangle, so the triangle is unique. If you can actually form a triangle with the given two side lengths and the angle measure of an angle that is not included, you can get more than one triangle. There … WebDec 9, 2024 · The simplest answer is that a pentagon has $5$ sides, $5$ angles. By extending the sides, you could get as many as $40$ angles ($4$ per intersection of $2$ lines, $\binom {5} {2} = 10$ intersections). Pentagons with $2$ parallel sides will have $36$ angles (those $2$ lines will not intersect). – Joshua Wang. Dec 9, 2024 at 17:17.
